If walking several miles to play a round of golf is too difficult, there are shorter versions, such as Pitch and Put, played on a golf course with holes typically less than eighty yards long, only requiring a pitch and a put. These are sometimes called par-3 courses.
An even shorter course is used in Mini-Golf (also going by the name Crazy Golf, Miniature Golf and Putt-Putt), which only requires the putting part of the game. This game is usually played on artificial surfaces, sometimes on pool tables with pool cues like Mini-Golf Billiards. There are other similar putting types of sport, such as Behcup, which using the putting motion though the balls are hit into a small goal rather than into a hole.
Other elements of the game of golf have been utilized to create unique sports. There are Longest Drive competitions, and the sport of Target Golf where players hit a golf ball at a large net, scoring points based on where the ball lands.
Golf is traditionally played on grass, but there are other versions played on different surfaces. In Winter there may not be grass available, but that shouldn't stop you from playing golf. You can play Snow Golf, just like regular golf, however the golf course is covered with snow and ice. The summer variation of this is Beach Golf, a simplified version of golf played on sand with a polyurethane foam ball.
Large open areas are difficult to find in the increasingly urban world. The answer is Urban Golf, golf played anywhere that there's free space (and preferably not too many people about), with anything possible as an obstacle.
Park Golf is a simplified version of golf invented in Japan, played with a single club and ball and resembles a long version of croquet. Croquet has a lot of similarities to golf, and a popular form of croquet is called Golf Croquet, in which each player takes a stroke in turn, trying to hit a ball through the same hoop. Another sport described as a mix of croquet and golf is the sport of Krolf from Denmark, where players use a mallet to hit the ball into a hole.
